5. Caroline Lake:
Adaptation Demonstration
•1,044 acres of working forest
▫ Owned by TNC since 1997
▫ Managed by Compass Land Consultants
▫ ONE MORE BULLET?
•One of first ever on-the ground climate
change adaptation demonstrations
▫ Climate-informed management plan
▫ Implement adaptation practices

6. Leveraging Forest Inventory Data
How can we better use forest inventory data to tell us:
1) Are forests are at risk from climate change?
2) Are management actions reducing risk?
8. Rethinking Existing Inventory Metrics
TNC’s Two-Hearted property in Upper Michigan:
TNC & Compass identified metrics to evaluate old-
forest characteristics of northern hardwood forests
• Robust inventory provides
starting point
9. Rethinking Existing Inventory Metrics
Two-Hearted Inventory:
• Total Stocking
• Acceptable Growing Stock
• Tree Species Diversity
• Tree Species Evenness
• Large Live Trees
• Large Snags
• Large Coarse Woody Debris
• Established Seedlings
• Desirable Established Seedlings
What do these metrics tell us about
climate change? What’s missing?
10. Climate-Informed Metrics
Traditional Metrics: Repurposed New Risk Metrics
• Total Stocking(1)
• Tree Species Diversity
▫ Richness(2)
▫ Evenness (3)
• Large Coarse Woody Debris (4)
• Regeneration
▫ Saplings(5)
▫ Seedlings(6)
• Risk of Decline
▫ Trees (7)
▫ Saplings (8)
▫ Seedlings(9)
11. Examples of Repurposed Metrics
Inventory
Metric
Typical* forest
inventory?
Normally would be
used to…
In the context of climate
change…
Tree Species
Richness
Tree Species
Evenness
No:
Data collected,
but often not
evaluated
Give an indication of
stand- or forest-level
diversity
Higher species evenness and
richness may have greater
adaptive capacity/ lower risk
Regeneration Sometimes, but
often not
Show effectiveness of
regen treatments;
inform future actions
Regeneration may be most
influenced by climate change;
potential early indication of
change or future issues
*Don’t take offense– you might not be “typical”
12. New Risk Metrics
Are the trees in this stand/forest/area at
risk from climate change?
•Integrates Climate Change Tree Atlas projections, which
are part of published vulnerability assessments
•“At risk” species identified for an ecoregion
▫ Suitable habitat reduced >20% by 2100
•IMPORTANT: Metric signals that species is at risk of
decline across a general region, but it is up to manager
to evaluate that information given local knowledge

How can we use climate change information
to assess risk from climate change?
to inform management actions?
to evaluate success over time?

28. Climate-Informed Metrics
Many potential metrics, but much of
the interest/discussion has been
centered on the risk metrics.
Why risk?
• Risk is a clean, crisp word that
resonates with certain folks
• Risk is just a statement―there’s no
value judgement (winners, losers)
or implied recommendation
(e.g., disfavor losers)
New Climate-Informed Metrics
• Stocking/Relative Density of
Adaptation-Target Species
• Risk of Decline – Trees
• Risk of Decline – Established
Seedlings
• Risk of Decline – Unestablished
Seedlings
• Tree Vigor
• Forest Vigor
• Canopy Closure
Many potential metrics, but much of interest/discussion focused on species risk metrics
